Abstract

A new hybrid cell line, designated NG115-401, produced a significant amount of immunoreactive (IR) substance P-like material. The production was measured by radioimmunoassay using specific antisera raised to substance P. The production rate was dependent upon cell growth, and maximum production occurred at the same stage (late logarithmic stage) as the time of appearance of choline acetyltransferase activity, one of the characteristic neuronal properties of the cells. On the other hand, no IR-substance P was found in hybrid cells other than NG115-401, i.e. NG115-301 and NG115-303 cells, which were derived from the same parent mouse neuroblastoma N115TG-2 cells. Furthermore, in an attempt to survey IR-substance P production in several clonal cells, consisting of some mouse neuroblastoma cells and a rat glioma cell, and several of their hybrid cells, we could find no cell line producing a significant amount of IR-substance P except for NG115-401 hybrid cells. The cellular production of IR-substance P in NG115-401 hybrid cells was also confirmed by detecting the material in all 14 subpopulations of this hybrid cells. Partial characterization of IR-substance P-like material produced by NG115-401 hybrid cells was carried out by its ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
